Which is an example of chemical weathering?

Hydrolysis

Explanation:

Chemical weathering refers to the weakening, breaking down and subsequent disintegration of rock due to different chemical reactions and  alters their constituent minerals. Examples are:

To focus on one of the examples, hydrolysis is the breakdown of a substance when it is combined with water. There is a chemical reaction between the minerals found in a rock and water. When it rains, water seeps down into the ground and comes in contact with granite rocks which reacts with the water. Then it is chemically altered to form clay minerals, which weaken the rock.

This process occure faster at higher temperature, so warm, damp climates are best. And most notably , hydrolysis and also oxidation are the first stage in the production of soils.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
